摘要
对风积砂地基扩展基础在上拔荷载作用下进行了室内模型试验 ,分析研究了土中应力、位移、破坏形式 ,并提出其强度机理及极限上拔力的计算公式。
L aboratory model test is conducted on enlarged foundation in wind carried sand ground under the function of pull up load and the stress,displacement,type of failure in soil are analyzed.The strength mechanism and the calculation formula for ultimate pull-up force are given.
